Setting Up the SAP System for SNC Connections
If you want to use SNC connections with the SAP system, you must configure the SAP system to accept both SNC and non-SNC connections from Adapter for SAP.
When connecting to the SAP system, Adapter for SAP creates two types of connection pools for each connection alias: an SAP repository connection pool and an SAP runtime connection pool. The following table describes each adapter connection pool.
Connection Pool Type | Description |
Repository | ![*](chapterTOC_bullet.png) Used internally for metadata lookup ![*](chapterTOC_bullet.png) No business data is processed over the connections ![*](chapterTOC_bullet.png) Supports both RFC and SNC connections |
Runtime | ![*](chapterTOC_bullet.png) Managed by the Adapter Runtime ![*](chapterTOC_bullet.png) All business data is processed over the connections ![*](chapterTOC_bullet.png) Supports both RFC and SNC connections |
To use SNC connections, you must configure the following settings in the SAP system.
